ALBERT G-ARSKE, OF REEDSBURG, WISCONSIN.

SPARK ARRESTER AND EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 696,960, dated April 8, 1902.

Application filed May 31,1901.

To aZZ whom it may concern:

Be it known that I, ALBERT GARSKE, a citizen of the United States of America, and a resident; of Reedsburg, in the county of Sauk, State of Wisconsin, have invented certain new and useful Improvements in Spark Arresters and Extinguishers, of which the following is a full, clear, and exact description, reference being had therein to the annexed drawings, in which- Figure 1 is a side elevation of my device, and Fig. 2 a transverse vertical section taken on the line 2 2 of Fig. 1. Fig. 3 is a vertical sectional view of a portion of a boiler and smoke-stack provided with my invention.

The object of this invention is to provide a simple device for arresting and throwing back and deadening the sparks before they leave the smoke-stack.

This invention consists in its preferred form of a clamp (1, adapted to be clamped to the exhaust-pipe in the smoke-box of a locomotive or a traction-engine boiler and to be vertically adjustable thereon. Bolted or riveted to the upper edge of the clamp are a series of three rods 1), which are of sufficient length to extend up into the smoke-stack when the device is in place in the smoke-box. Bolted or riveted to the upper ends of these rods is an inverted cone 0, which is supported centrally within the rods. Around the upper part of this cone 0 and parallel with its base are several rows of nails or brads f, the nails in each row alternating with those in the row above them and being inserted from within and projecting at right angles to the outside surface of the cone, the heads of the nails or brads being held down in place by another cone of the same size placed within it and resting against the nail-heads, or, instead of nails, screw-bolts, to be screwed directly into the cone, or other pins or projections may be employed. The rods pass through the vertical draft-tube d, which is in form the frustum of a cone and is supported by said rods within the lower end of the smoke-stack and Serial No. 62,501- (No model.)

directly over the exhaust-pipe, so that the exhaust-pipe will discharge up through it. The rods are bolted adjustably to the interior of the tubed, so that they and the clamp may be vertically adjusted to bring the conical arrester c at the proper point with respect to said central draft-tube, and the device at the top is held centrally in the smokestack by means of rods 6, bolted 0r riveted to the inside of the cone 0 and extending to and resting against the inside of the smokestack.

It will be observed that the sparks are directed against the bradded cone and are thereby thrown back and deadened.

Having thus fully described my invention, what I claim, and desire to obtain by Letters Patent, is

1. In a spark-arrester, the combination of a series of supporting-rods provided with means at their lower ends for securing them to a support, a draft-tube supported on the rods, and an inverted cone supported above the draft-tube and provided with numerous outward-extending pins.

2. In a spark-arrester for smoke-stacks, the combination of a series of rods provided with means for adj ustably securing them to a support at their lower ends, a draft-tube sup ported on the rods intermediate their. ends, an inverted coneattached to theupper ends of the rods above the draft-tube and provided with numerous outward-extending pins, and means for centering the apparatus in the smoke-stack consisting of a series of fingers attached to the inverted cone and extending upward and outward and adapted so as to bear movably against the interior of the stack.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 27th day of May, 1901.

ALBERT GARSKE.
